HINGED WlNDOW-SASH.

SPECIFICATION forming part of Letters Patent No. 385,577, dated JulyT 3, 1888.

Application filed August 3, '1887. Serial No.24i`n012. (No model.l

To all whom it may concern.:

Be it known that I, WILLIAM L. SILBER EISEN, of Brooklyn, in the county ofKings and State of N ew York, have invented certain new and useful Improvements in Hinged Window- Sashes, and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in which Figure l is a front elevation in perspective of a window-casing fitted with my invention. Fig. 2 is a vertical section in line w w of Fig. l; Fig. 8, a vertical section in line x ."0 of Fig. 2; Fig. 4L, a transverse horizontal section in line y y of Fig. l. Fig. 5 is a detached scctional view, on an enlarged scale, of the device for attaching the sash-weight to the hinged sash; Fig. (i, a plan View, on an enlarged scale, of my improved catch and lock; and Fig. 7, a section thereof in line z e of Figf.

Myinvention relates to the construction and arrangement of window -sashes adapted to swing outwardly, and also slide vertically in the window-casing, and has for its object to facilitate, in a simple effective manner, the use of windows which may not only be raised and lowered in their frames and counierbalanced by weights, but will also admit of being swung in or out upon hinges at any height to which they are raised in the casing, and of bcing locked and fastened in a tight, secure manner, so as to be free from rattling.

' lt consists in the combination,with windowsashes sliding and turning upon vertical rods, of novel devices, substantially as hereinafter described, for attaching countcrbalancing weights to said sashcs, to operate without interference with their swinging movement, and for tightening the sashes in the casing, so as to prevent them from rattling, and also lock and secure them against burglars.

In thc accompanying drawings, A represents the frame or casing of a double window, B B its two lower sashes, and O O its two upper sashes.

The corresponding upper and lower sashes, B and C, on each side are hinged severally upon two parallel rods, D D, fixed at top and bottom in the upper and lower bars of the window frame or casing, near to and parallel with the side bars, E E, of the casing, and which pass through longitudinal perforations in the inner side bars ofthe sash. (See Figs. 1, 4, and 5.) To obtain the utmost rigidity without undue weight in these hinged rods D.

D, I prefer to make them tubular, as shown in Figs. 4 and 5.

To permit of an attachment of the ordinary sash-weight cords, F F, to the sashes,thus severally hinged each upon a vertical rod,D,with out interfering with the movement of the sash upon its hinge, a horizontal recess, a, is cnt in the hinged bar of each sash, near to the top thereof, to extend from side to side in a halt" circle about the hinge-rod. rThis recess is made long enough to receive freely the head of aT-shapedlng, G, projecting from a block, II, to which the inner end of the sash-cord F is attached. (See Fig. 5.) The recess a is covered by a metallic plate, b, having a hori- Zontal slot therein adapted to embrace the shank of the lng, yet allow it free movement, and this slot terminates at one end in an opening, c, (see Fig. 5,) sufficiently enlarged to allow the head of the lug G to pass freely through it. By this means the head of the lug is readily inserted into thc recess, while the stem of the lng is left free to play in the longitudinal slot as the window swings on its pivot, the enlarged head preventing a disengagement ofthe lug at any point until the window is swung in one direction to its fullest extent. The sashcord F, thus attached to the sash by the block H and its lug G, is carried over an upper pulley, J,

and made fast to a weight, K, adapted to conn-` terbalance the sash in the customary manner.

When it is desired that either of the sashes shall swing in both directionsinward and ontward from the casing, the sash is hinged in the customary manner to a strip, L, (see Figs. l and 4,) which is itself in turn pivoted upon oneV ICO (See Fior. 3.) Im- I insert in the same recess a second parallel strip, N, which is preferably connected with the outer strip, M, by a longitudinal tongueand-groove joint. (See Fig. 4.) rIhis inner strip is made shorter than the outer strip, and is left free to slide longitudinally up and down over the saine.

Upon the opposite contacting faces of the two strips I form a series of opposed inclined surfaces, c c e f f f, with intervening recesses h 7L h, having parallel flat surfaces, (see Fig. 3,) whereby,when the inner strip, N, is moved longitudinally, the movement of its inclined faces c e over the opposed inclined faces ff of the outer strip, M, will operate to wedge out the la-tter and force it tightly against the sash.

The inner tightening-strip, N, is moved up and down, as required to tighten or to release the sash,by means of a notched plate, O, at the lower end thereof, (see Fig. 2,) which is engaged by a toothed wheel, I), actuated by a crank, Q, projecting outside of the windowframe. Vvhen the vertical tightening-strips are used for both upper and lower sashes, the inner strips, N N, may be both connected to a single notched plate O, to be operated by a single crank Q, as shown in Fig. 2.

The two lower sashes, when lowered and closed, may be fastened and secured by means of a swinging bar, R, hinged in a recess in the top of the upper-bar of one of said sashes, to turn down into a recess cut in the top of-the upper bar of the other sash, as shown in Figs. l and 4, and the sashes are locked and drawn tightly together, so as to make a close joint along the meeting-rail by means of a catch or hook, S, (see Figs. 4 and 6,) pivoted to swing loosely in a horizontal plane upon a pivot consisting of a disk, T, pivoted eccentrically upon a plate, U, by which it is secured to the upper edge of the lower bar of the upper sash in position to permit the catch or hook S to swing out over the top edge ofthe upper bar of the lower sash and engage a pin or knob, 1'., (see Fig. 4,) on the edge ofthe swinging lock-bar R when the bar is dropped into its horizontal position to fasten the window, as shown in Fig. 4 and by dotted lines in Fig. l. rlhe eccentrically-pivoted disk T is turned upon its pivot by a thumb-piece, W, or byalever projecting therefrom, and by turning the disk the hook is thrown out from and drawn toward said disk, (see dotted lines, Fig. 6, illustrating said movement,) and may be consequently'carried out beyond or drawn into close contact with the knob or catch-pint` on the window-sash when swung into position to engage the same, the hook S being swung into position by simply turning it about the disk as its pivotal center. rlhis form of catch turning freely upon an ec centrically-pivoted pin or disk, itself turned by a thumb piece or lever, to throw the swinging hook in and out of position to engage a catch-pin, may evidently be employed to draw and lock together the upper and lower sashes independently of the swinging bar R, as well as in other connections, and I purpose making the same the subject of a separate application for Letters Patent.

I-Iaving thus `fully described my invention, I claim therein as newl. The combination,witha window-sash and its easing, a vertical rod secured in the casing, and upon which the window-sash is pivoted and left free both to swing and to slide longitudinally, and a counterbalanei ng sash weight and cord mounted in the casing, of a block pro vided with a T-shaped lug or button and a slotted plate fitted over a recess in the inner edge of the pivoted sash, through which the shank of the lug orbutton is free to play in a direction transversely to the Divotrod as the sash turns thereon, substantially in the man ner and for the purpose herein set forth.

2. The combination, with the easing of a window and with a sash sliding and turning upon a vertical rod secured in said casing, of a strip fitted in a recess in the casing independently of the sash, to move laterallyin and out against the proximate pivotcd bar of the sash, a second strip moving longitudinally in said recess against the inner face of the outer strip, and a device, substantially as described, for moving said inner strip, the opposite faces of the two strips being formed with a series of o5 y WM.
